Description

We have a grouping field which we defined as an integer; when we run a query grouping on that field it works fine in a non-cloud configuration, but when we try the same query in a SolrCloud configuration with multiple shards, we get the following error:

Type mismatch: <fieldName> was indexed as NUMERIC

Schema:

<dynamicField name="*_i"  type="int"    indexed="true"  stored="true" docValues="true"/>

Query:

q=*:*&group=true&group.field=<fieldName>&group.limit=1
